Excerpt: The charging and data connector is Kyocera proprietary, but if you do a Google or Amazon search you will find the chargers, although they will be quite expensive. Make sure, however, to double check with the vendor, because many sellers think that this phone uses a standard Micro USB charger, whereas it's a unique, proprietary charger that will only work with the E3500.
Excerpt: The phone is OK, but the cable that connects it to your computer or charger is TOTALLY proprietary and you cannot find them anywhere - It says "mini USB" in the manual, but it is neither mini or Micro USB. It is Kyocera propietary - and not only that, but apparently almost all the Kyocera phones have different plugs..If you buy this phone, be prepared to pay $20-30 every time you lose your cable....dont buy this phone.
Summary: Right now, I'm using it as a phone, but I'm still digging throught the 60 page manual to learn to use all of the other features on this device. The only downside is the main directional button; sometimes when I press "OK" it reacts as a "down" key - probably a personal problem, but slightly annoying. Everything else seems great - I just need to learn how to use everything!
